Book Synopsis Larvae and Evolution by : D. Williamson

Download or read book Larvae and Evolution written by D. Williamson. This book was released on 2013-03-09. Available in PDF, EPUB and Kindle. Book excerpt: Many biological facts are irreconcilable with the assumption that larvae and adults evolved from the same genetic stock. The author of this book draws attention to these, and presents his alternative hypothesis that larvae have been transferred from one taxon to another. In his previous book (Larvae and Evolution, 1992), the author used larval transfer to explain developmental anomalies in eight animal phyla. In the present book, he claims that the basic forms of all larvae and all embryos have been transferred from foreign taxa. This leads to a new, comprehensive theory on the origin of embryos and larvae, replacing the discredited 'recapitulation' theory of Haeckel (1866). Metamorphosis, previously unexplained, represents a change in taxon during development.

Book Synopsis The Origin and Evolution of Larval Forms by : Brian K. Hall

Download or read book The Origin and Evolution of Larval Forms written by Brian K. Hall. This book was released on 1999-01-12. Available in PDF, EPUB and Kindle. Book excerpt: A classic problem in evolutionary biology is the origin of larvae - how and why did they occur? Indeed, it has often been suggested that many entirely unique body plans first originated as retained larvae of ancestral organisms. But what of the larvae themselves? What developmental and evolutionary forces shape and constrain them? These questions and others are dealt with by this international team of leading zoologists and developmental biologists. Intended to contribute to a continuing dialectic, this book presents diverse opinions as well as manifold conclusions. Certain to challenge and intrique, The Origin and Evolution of Larval Forms should be a part of the library of every evolutionary and developmental biologist interested in larvae and their significance.

Book Synopsis Evolutionary Ecology of Marine Invertebrate Larvae by : Tyler J. Carrier

Download or read book Evolutionary Ecology of Marine Invertebrate Larvae written by Tyler J. Carrier. This book was released on 2018. Available in PDF, EPUB and Kindle. Book excerpt: "More than seventy percent of the earth's surface is covered by the ocean which is home to a staggering and sometimes overwhelming diversity of organisms, the majority of which reside in pelagic form. Marine invertebrate larvae are an integral component of this pelagic diversity and have stimulated the curiosity of researchers for centuries. This accessible, upper-level text provides an important and timely update on the topic of larval evolution and ecology, representing the first major synthesis of this interdisciplinary field for more than 20 years. The content is structured around four major areas: evolutionary origins and transitions in developmental mode; functional morphology and ecology of larval forms; larval transport, settlement, and metamorphosis; larval ecology in extreme and changing environments. This novel synthesis integrates traditional larval ecology with life history theory, evolutionary developmental biology, and modern genomics research to provide a research and teaching tool for decades to come." -- from the rear cover.
